WINDOW CLEANING DEVICE.

Specification of Letters Patent.

Patented Feb. 25. 1913.

Application filed May 4 1912. Serial No. 695,083.

To all whom it may concern Be it known. that I, CLAUDE L. ROBINSON, acitizen of the United States, residing at Princeton, in the county ofDade and State of Florida, have invented new and useful improvements inWindow-Cleaning D e vices, of which the following is a specification. 7

This invention relates to window cleaning devices and particularly todevices designed for use upon street cars, automobiles or like I windowswhere it is desirable to maintain a perfect transparent condition of theWindow in immediate line with the face of the driver or operator.

An object of the invention is to provide a window cleaning device whichmay be slidably mounted upon a window frame and which will beautomatically held in an operative position at one end of the frame soasto permit of its being readily drawn across the window as the occasionmay demand.

A still. further object of the invention is to provide a window cleaningdevice which will include an elastic gripping element and means wherebythe element. can be rocked with relation to the window and automaticallybrought into operative contact with the window or movement of the devicein one direction and then automatically moved toa disengaged position onmovement of the device in another direction.

In the drawing forming a portion of this application ,and in which likeletters of reference indicate similar parts in the several views :Figure1 is a front view of a windowshowing the application of the cleaningdevice thereto. Fig. 2 is a section on line 22 of Fig. 1. Fig. 3 is aperspective view of a portion of the carriage. Fig. 4 is a'section takenon line 4-4 of Fig. 1 drawing the cleaning strip in contact with ctransparent panel of the window. Fig. 5) is a similar view showing thecleaning strip disengaged from the transparent panel of the window.

The cleaning device preferably comprises :2 carrier which includes a rod1 which is disposed vertically upon the window frameitconventionallyshownhercin. 'lhisrodhas socket. nuuubcrs 2 securedthereto at its ends and as illustrated the socket members are providedwith slots 3 through which combined guide and stop pins 4 of slidablestub shafts 5-extcnd. These shafts have port-ions.

extended into the sockets 2 and outwardly of the sockets they areprovided with outwardly diverging arms 6 upon which rollers 7 arejournalcd. being adapted to travel upon the tracks 8 for a purpose to behereinafter described.

A sleeve 9 is mounted for-rocking movements upon the rod 1, beingpreferably provided with extension 10 to which is secured an elasticcleaning strip 12. Fastenin screws or the like 13 are extended througithe strip 12 and extension 10 so as to hold the-former properlyassociated with the lat.- ter. The socket portions 2 are provided withsteps 14 with which the sleeve 9 is adapted to contact whereby themovement. of the latter is limited in one direction.

Brackets 14 are secured to the rails S and journaled therein are pintles15 of a roller 16. This roller has one endof a helical spring 17 securedtherein while the opposite end of the spring is secured to one of thepintlcs so that under the action of the spring the roller will tend torevolve in one direction. Cords 19 are secured to and wound around theopposite ends of the roller and extended through passages 20 in theextension 10 of the sleeve 9. One cord is referably extended through oneof the sir e bars of the window frame and operatively passed throughguide eyes 22 which extend from the frame while the free terminal ofthis cord is detachably connected with a suitable cleat or retainingdevice 23 near the lower edge of the frame. The other cord 19 is securedto the just described cord as at 24: whereby when the cleat engagingterminal 25 is pulled both the cords may be unwound from the roller anddrawn across the transparent 'panel of the window. Each cord is providedwith a pair of spherical objects or sleeve 9 in a direction to cause thestrip 12 to move. in spaced relation to the said transparent panel ofthe window. When the terminal 25 is released the (-ordswill be drawnback upon the roller under the tension of the spring 16. The bodies 26will be made to engage with the extension 10 of the sleeve 9 so as torock the same in one direction on the rod '9 with a resultant engagementof the strip 12 with the transparent panel of the Window. Relativelystrong springs 28 are mounted in the socket portions 2 of the rod 1.These springs are made to engage -against the inner ends of the stubshafts 5 in a manner which will cause them to be forced outwardly. Thiscauses the rollers 7 to effectually engage against the rails 8hereinbefore described.

I claim A Window cleaner comprising parallel tracks, a rod extending atright angles to the tracks and provided at its ends with socketportions, traveling supports movably engaging the tracks, and havingportions yieldingly fitted in said socket portions, means for moving therod in two directions, and a rocking strip carried by the rod andadapted to engage against the window pane on movement of the rod in onedirection.
